M1 through M7 are displayed in the instrument
cluster.The transmission provides assistance in the fol-
lowing situations:
>Upshifts and downshifts are executed only
when they will result in a plausible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>When the vehicle stops, the transmission
automatically shifts down to first gear.
>Shortly before the vehicle slows down to
below the minimum speed of the gear cur-
rently engaged, the transmission automati-
cally shifts down without requiring your
intervention.
Rapid downshifting: in manual mode, you can
skip several gears to achieve optimal accelera-
tion. Do so by pressing the accelerator past the
resistance point.
Changing to drive mode
Push the selector lever to the right.
Shifting gears via the selector lever
In manual mode:
>To shift up, pull back the selector lever.
>To shift down, push it forward.
Shifting gears via the shift paddles on
the steering wheel
The shift paddles allow you to shift gears with-
out taking your hands off the steering wheel.
You do not need to raise your foot from the
accelerator when doing so.
>To shift up: press one of the shift paddles

dles forward, arrow2.
Gears can be shifted using the shift paddles in
drive mode or in manual mode.
Gear change in manual mode:
When manual mode is active, refer to page57,
gears can be changed using the shift paddles or
the selector lever.
Gear change in drive mode
The shift paddles can be used to change gears
in drive mode as well.
Afterwards, if the shift paddles are not used for
some time and vehicle acceleration is insuffi-
cient, the forward gears are changed again
automatically.
Launch Control
Launch Control enables you to drive off with an
optimal vehicle acceleration on a high grip road
surface.
Do not use Launch Control too often, as
the higher loads on the vehicle lead to
premature component wear.<
Launch Control is available when the engine is
at operating temperature, i.e., after driving con-
tinuously for at least 6 miles/10 km.
1.With the engine running, depress the brake
pedal with your left foot.
2.Activate the SPORT+ program of the
Dynamic Driving Control, refer to page79.
3.With the vehicle stationary, activate manual
mode and select first gear.
4.Press the accelerator all the way down. The
engine speed when driving off is controlled.
A flag symbol appears in the instrument
cluster.
5.The vehicle accelerates when you release
the brake pedal. Keep the accelerator
pressed all the way down.
6.The transmission shifts up automatically as
long as the accelerator is pressed all the
way down.Launch Control only becomes available again
after a certain distance has been driven.
Launch Control can only be used after the
break-in phase, refer to page112.
To maintain driving stability, activate DSC
whenever possible.<
Manually releasing and engaging the
transmission lock
If a power failure occurs, e.g., if the battery
is discharged or disconnected or if there
is an electrical malfunction, the transmission
lock must be released manually; otherwise, the
rear wheels are blocked and the vehicle cannot
be towed.<
Release the transmission lock manually for tow-
ing only and set the parking brake beforehand
to prevent the vehicle from rolling. After parking
the vehicle, lock the transmission lock again
manually, refer to page59.
Manual release
1.Unclip the sleeve of the selector lever.
2.Pull the sleeve up over the selector lever
until the sleeve is inside out.
3.Insert the Allen wrench from the onboard
vehicle tool kit, refer to page212, into
the cap.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduc ed by up to 5 mph o r 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
>When you engage selector lever position N
in cars with an automatic transmission
>When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
>When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.

Things to remember when driving
114 The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page198.
Driving through water
Drive though calm water only if it is not
deeper than 1 ft/25 cm and at this height
no faster than walking speed, up to 6 mph/
10 km/h. Otherwise, the vehicle's engine, the
electrical systems and the transmission may be
damaged.<
Use the parking brake on inclines
On inclines, do not hold the vehicle for a
lengthy period using the clutch; use the
parking brake instead. Otherwise, greater
clutch wear will result.<
For more information about the drive-off assis-
tant, refer to page80.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors. Full
braking efficiency will then be available when
you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even light but consistent brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page54.
7-gear sport automatic transmission with
dual clutch: Never drive with the trans-
mission in neutral or with the engine switched
off; otherwise, engine braking action will not be
present or there will be no power assistance to
the brakes or steering.
Manual transmission: Never drive with the
clutch held down, with the transmission in neu-
tral or with the engine switched off; otherwise,
engine braking action will not be present or
there will be no power assistance to the brakes
or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals; otherwise, pedal function could be
impaired.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail
to cure.
When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
